How to use supercontinent in a sentence

Looking for sentences and phrases with the word supercontinent? Here are some examples.

Sentence Examples Amalgamation of the late Palaeozoic supercontinent Pangaea led to the collision of Gondwana with Laurasia forming the Variscan orogen. The salt was formed in a sea that existed when the supercontinent Pangea broke up some 200 million years ago. Recent palaeomagnetic and geodynamic constraints envisage an early Mesoproterozoic supercontinent that at least included Laurentia and Baltica. The hundred million years and more of Pangean history saw a succession of cosmopolitan animal dynasties spread over the entire supercontinent. At longer time-scales, plate tectonic activity appears quasi-periodic and self-organizes into the supercontinent cycle. When New Zealand split away from the supercontinent Gondwana some 80 million years ago, its flora and fauna were left to develop in isolation. Of the three domains, the Eastern Domain sits farthest inboard, i.e. closest to the core of the former Gondwana supercontinent. Geological evidence shows that all continents remained united as the supercontinent Pangea during Triassic times. It's believed to be a supercontinent from before the Triassic period that included all of the continents we know today in one giant landmass! Thus, as oceanic lithosphere formed by supercontinent dispersal ages, it has a tendency to subduct, possibly at fracture zones. Together with the Appalachian, Caledonian and Variscan orogens, the Uralian orogeny contributed to the assembly of the late Palaeozoic supercontinent of Pangaea. This change may be related to the opening of the Atlantic Ocean which accompanied the break-up of the supercontinent Pangea. During the Permian, India was a part of the Gondwanan supercontinent. It cannot, reckons Dr Rogers, be a coincidence that a single supercontinent with a Pangaea-like configuration emerges time and time again. By the beginning of the Cretaceous, the supercontinent Pangea was already rifting apart, and by the mid-Cretaceous, it had split into several smaller continents. If the past pattern holds, Dr Rogers predicts that a new supercontinent will be formed in about 500m years' time. The extinction occurred at the boundary between the Permian and Triassic periods at a time when all land was concentrated in a supercontinent called Pangea. About 500m years later, its pieces reassembled to form yet another supercontinent, called Rodinia. The birth of the Cordillera occurred when the supercontinent Rodinia split apart about 700 million years ago. The paleogeographic record of the Earth shows that periodically all of the continents cluster into a single supercontinent. Show More Sentences Destined for a broad public, shows the nine most important stages in the break-up of this supercontinent, on the basis of recent scientific work. Some 250 million years ago, all the continents were grouped into a single supercontinent known as Pangaea. The continents of the Earth had fused into the most recent supercontinent to have formed, Alfred Wegener's Pangea. For me, the main message of the supercontinent cycle is humility before nature, and to the depth of time. The Caledonian orogeny was one of several orogenies that would eventually form the supercontinent Pangaea in the Late Paleozoic era. During the Permian, all the Earth's major landmasses were collected into a single supercontinent known as Pangaea. A larger supercontinent will therefore have more area in which climate is strongly seasonal than will several smaller continents or islands. Geologists tend to study plate tectonics, meteorites from outer space, and resources from the breakup of the supercontinent Gondwana. Pangaea was the most recent supercontinent to have existed and the first to be reconstructed by geologists. Paleomagnetic study of apparent polar wandering paths also support the theory of a supercontinent. The ridge is central to the breakup of the hypothetical supercontinent of Pangaea that began some 180 million years ago. There is thus a relatively simple relationship between the supercontinent cycle and the mean age of the seafloor. During the Carboniferous, Laurasia and Gondwana collided and thus began the formation of the supercontinent Pangea. All six groups of diamonds were found in areas that would once have lined the edge of the ancient supercontinent Gondwana. Diversity, as measured by the number of families, follows the supercontinent cycle very well. At this point in time the area would have been positioned around the equator and would form part of the Pangaea supercontinent. The rodent fossil record dates back to the Paleocene on the supercontinent of Laurasia. As a result, the mantle beneath the supercontinent becomes anomalously hot, and vast volumes of basaltic magma pond beneath it, forcing it to arch up and crack. In addition, new collisional events led to the formation of Gondwana, a supercontinent composed of what would become Australia, Antarctica, India, Africa, and South America. Within the supercontinent interior large sedimentary basins developed at this time, whereas post-Permian turbidite deposits on the oceanic fringe represent large volumes of accreted material, possibly allochthonous. Show More Sentences Gondwana, also called Gondwanaland, ancient supercontinent that incorporated present-day South America, Africa, Arabia, Madagascar, India, Australia, and Antarctica. While the Cimmerian continent was drifting northward, a new ocean, the Neo-Tethys, was opening behind it and north of the Gondwanaland supercontinent. These plates move and collide, at times merging to form a single supercontinent, the last of which is known as Pangea and disappeared 130 million years ago when the Atlantic opened up. It was believed to have been caused by a slowly drying climate that was the result of continental drift bringing all of the Earth's land together into an enormous supercontinent. Could these represent times of supercontinent dispersal? Although the existence of a Neoproterozoic supercontinent Rodinia is still hypothetical, the existence of a ca. 550 Ma Pannotia supercontinent is the major question. It also intends to determine whether the Palaeoproterozoic cratons originated by breakup of an older, pre-Rodinia supercontinent or were independent fragments of continental crust. In ten steps, The Changing Face of the Earth traces continental shift since the Pangaea, a single supercontinent, began breaking up 250 million yeas ago. Then, some 360 million years ago, after the Appalachians formed, all the continents once again came together, forming the supercontinent Pangaea, which subsequently broke up into the continents as we know them today. It was, like the various continents, a part of the supercontinent of Gondwana. The Gulf of Mexico did not exist 250 million years ago when there was but one supercontinent, Pangea. During this time, the supercontinent Pannotia begins to break up, most of which later became the supercontinent Gondwana. Geologically, the Paleozoic started shortly after the breakup of the supercontinent Pannotia. Towards the end of the era, the continents gathered together into a supercontinent called Pangaea, which included most of the Earth's land area. During the Permian and Triassic periods, with the Iapetus Ocean entirely closed, Scotland lay near the centre of the Pangaean supercontinent. Correlatives are known from Argentina, also in the center of the ancient supercontinent Gondwanaland. Shallow seas flanked the margins of several continents created during the breakup of the supercontinent Pannotia. New Zealand is part of Zealandia, a microcontinent nearly half the size of Australia that gradually submerged after breaking away from the Gondwanan supercontinent. Baltica, Laurentia, and Avalonia all came together by the end of the Ordovician to form a minor supercontinent called Euramerica or Laurussia, closing the Iapetus Ocean. This supercontinent included large amounts of land near the poles and, near the equator, only a relatively small strip connecting the polar masses. Show More Sentences By the beginning of the Jurassic, the supercontinent Pangaea had begun rifting into two landmasses, Laurasia to the north and Gondwana to the south. The continents of Avalonia, Baltica, and Laurentia drifted together near the equator, starting the formation of a second supercontinent known as Euramerica. With the supercontinent Gondwana covering the equator and much of the southern hemisphere, a large ocean occupied most of the northern half of the globe. At the beginning of this period, all continents joined together to form the supercontinent Pangaea, which was encircled by one ocean called Panthalassa. The Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of million years ago. The Nature article reveals new information about where titanosaurs lived and how the breakup of the Pangean supercontinent influenced species evolution. Examples from Classical Literature Around 315 million years ago, during the Pennsylvanian period of Earth's history, these regions formed the tropical belt of a huge supercontinent that straddled the equator.
